Unmanned remote survey system is proposed to measure distance and angle of the present position of micro-tunneling machine from any starting point of entrance. Cross type linear LED that can be controlled remotely is attached to the tunneling machine. Range finder and angle measuring devise fixed to internal of the pipe can scan the center of LED. Distance and angle measuring devises are disposed in the measurable position of the pipe, then the present position of tunneling machine can be calculated automatically from the measurements.

Attitudes and behavior within the store congestion of the store is a store in any manner affect the formation process of investigating synchronism in the control of the consumer appears to analyze the influence of enemy has its purpose. Store and spatial congestion factor of social behavioral factors also revisit the help of word-of-mouth is. Consumer groups with high and low groups of synchronism suggested. Social attitudes towards the store congestion significantly positive effect that I've shown, it was not significant spatial congestion. During a revisit of action is a statistically significant relationship that I've shown, is a significant effect of word-of-mouth relationship was not significant. Investigating the moderating effects of consumer synchronism result of high consumer groups a significant impact on the social congestion showed, at low spatial influence congestion.
